Lion tattoos, tiger tattoos and koi or Japanese carp tattoos are some of the common designs for tattoos that symbolize strength. They also symbolize courage, power and perseverance. Simple tattoo designs that signify strength are images of the Sun and Chinese symbols or characters that literally translate to strength.
The meanings of these tattoos are derived from traditional symbolism. For instance, in Chinese tradition, the tiger symbolizes fearlessness and strength and is one of the 12 zodiac animals. A koi is also known to represent strength and perseverance — a Chinese legend tells of a koi that succeeded in swimming to the falling point of the Yellow River, where it turned into a dragon.
